EchoTouch US06-12 Reflective Ultrasonic Level Transmitter



  • Proprietary Reflective Tech™
  • Range of up to 12m
  • Fast & accurate configuration

EchoTouch US06-12 Reflective Ultrasonic Level Transmitter

The EchoTouch US06-12 from Flowline is an intrinsically safe reflective ultrasonic level transmitter provides continuous level measurement up to 39.3’ (12m) with a 4-20 mA analogue signal output.

The fast and accurate configuration is controlled via its integral push button display module or WebCal software. The non-contact liquid level sensor features our proprietary Reflective Technology™ that delivers reliable level measurement in condensing environments. Select this sensor for bulk tanks with non-foaming or highly vaporous media such as chemicals, water, wastewater, and oil. Typical applications include bulk storage, neutralization tank, clarifier, and waste sumps.

Condensation is the most common variable in liquid level applications. Condensation attenuates the acoustic signal of ultrasonic sensors with horizontal transducers, weakening their signal strength and signal to noise ratio by up to 50%, and substantially reducing their measurement reliability. At the core of Reflective Technology™ is a simple fact. Unlike flat horizontal surfaces, significant water droplets cannot adhere to smooth vertical surfaces. By orienting the transducer vertically, condensation runs off the transducer and does not affect sensor performance. The unimpeded transmit and receive signals are redirected to and from the liquid off a 45º reflector, delivering reliable level measurement. Thanks gravity.

Features of the EchoTouch Reflective Ultrasonic Level Transmitter includes:

  • Offered in 6m (19.6’) and 12m (39.3’) measurement ranges.
  • Reflective Technology™ measures reliably with condensation
  • Corrosion resistant PVDF transducer with IP68 PP enclosure
  • Fail-safe diagnostics with selectable signal fail-safe outputs
  • LCD display indicates level in inches, meters, or percent of span.
  • HART communication in point to point and multi-drop modes
  • Narrow 3” (7.6cm) beam width for applications with limited space
  • Windowed enclosure cap provides liquid tight level indication.
  • Configuration via push button display or WebCal software.
  • Automatic temperature compensation from -40º to 80º C.
